"Stealth Armor Prototype Upgrade with Sonic Dampening Thrusters and Reto-Reflective Coating which adapts the suits tint to the surrounding environment for Stealth Capabilities."
―(Iron Man 3- JARVIS: A Second Screen Experience) The Mark XV's description in the JARVIS Application.

The Mark XV (Mark 15), also known by its codename as "Sneaky", is a Stealth Armor Prototype Upgrade, and was one of several new Iron Man Armors created by Tony Stark as part of the Iron Legion. The armor was created sometime after the Battle of New York.[1]

It was featured in Iron Man 3, and made its debut when Tony ordered J.A.R.V.I.S. to initiate the "House Party Protocol", in which it was activated along with the rest of the Iron Legion to aid Tony in his battle against Aldrich Killian.

The suit was named "Sneaky" for the built in Cloaking System within its armor that allows it to be much more sneaky than most other suits. The Mark XV has the ability to camouflage itself within its surroundings by lightening or darkening its chrome colored armor.

Sneaky is the first armor to be have a codename in the Iron Legion, and it is also the second armor to be given a name by Tony, the first being the Mark V.

Armor Design

The Mark XV's most notable features are its slim and smooth body armor. It has a chrome colored plating, which allows it to turn lighter or darker to suit its environment. The suit also features a different design for both gauntlets. The left gauntlet has blue lights & a skeletal appearance, while the right gauntlet has a more basic design. This is because the armor's left gauntlet could be equipped with an electric field, (like to the Mark XXXVII), an EMP, or a sonic pulse (like the Mark XLII). The suit's right gauntlet could be equipped with rockets, unlimited lasers, a battle blade, a grappling hook, a grenade, a cryo blaster, a tranquilizer gun, or a mini gun.

The suit is lighter than the usual Iron Man suit, to enhance its speed, agility, and to allow its stealth system to take effect and to easily cope with stealth missions. The suit retains its signature Repulsors, as well as its Chest Repulsor and its Vibranium Powered Arc Reactor, like its previous Mark suits.

Armor Features

The armor has a Cloaking System. It also has sonic dampening thrusters equipped on its back.

Donning System

The Mark XV, along with all the other newly built Mark suits, uses a more advanced technology that was based off on the Mark VII's technology, which is able to wrap itself around Tony's body, without the aid of robotic arms or any external mechanicals.

It can flexibly open itself to allow Tony to enter into the suit and automatically wrap itself around him, anywhere at anytime, much like the Mark XLII's technology and the other newly built Mark suits'.


Having been built to be lighter than the usual Iron Man suit, to help enhance its speed, agility, and stealth system's effects, the suit is still suitable for combat, despite its limited weapons, but is not as combat ready as the usual Iron Man suit. The suit is only suitable for stealth missions and is limited to heavy combat.


  • JARVIS OS: JARVIS is integrated into the armor.

Armor Composition

The armor is composed of a lightweight chromed gold-titanium alloy.

Armor Capabilities

  • Speed: Since the Mark XV has lightweight chromed gold titanium plates, its speed is greatly increased. Its speed may not match that of the Mark XL, but it can still fly swiftly and easily dodge obstacles thrown at it.
  • Agility: The suit is also very agile, able to do various maneuvers during flight.


  • Stealth: The Mark XV, was designed for stealth and was specially built in with a cloaking system within its armor, to enable stealth, unlike all the other previous Mark suits. Its cloaking system allows its chrome plated armor to lighten or darken depending on its environmental surroundings, enabling it to use stealth and become virtually invisible to go unseen in early enemy warnings. Most of the suit's energy is directed towards its cloaking system to be able to supply it with enough energy to enable it to function well and run smoothly during stealth missions.


Since the suit was built for stealth, it has limited weapons. But it is still combat ready and has a few weapons equipped on it. It also retains its signature weapons, which are the Repulsors on its feet and hands, as well as the one on its chest which is called the Unibeam.

  • Repulsors: The Mark XV's Repulsors and its Chest Repulsor, retain the signature repulsors from the previous Mark suits and has the same power level from before. The Repulsors on its hands can be used as a powerful weapon as well as a source of thrust during flight, and the ones on its feet are used for flight stabilization and can also be used as a weapon.
  • Unibeam: The Chest Repulsor, can be used as well as a very powerful weapon, but only in dire situations or when needed, as it drains the suit's power faster than the regular repulsors on its hand and feet.
  • Other Weapons: The Mark XV, is also equipped with other weapons, but it is unknown what these weapons may be. The weapons of the left gauntlet may include an electric field, (like to the Mark XXXVII), an EMP, or a sonic pulse (like the Mark XLII). The suit's right gauntlet could be equipped with rockets, unlimited lasers, a battle blade (like the Mark XXXIII), a mini gun (like the Mark XXII), a grappling hook, a grenade, a cryo blaster, or a tranquilizer gun, attached to suit's external structure.


Before Iron Man 3

The Iron Legion and Creation

Sometime after the Battle of New York, Tony Stark, who was haunted by his near death experience from the event, suffered from post traumatic stress disorder and became obsessed with security.

Because of this, Stark began working on the Iron Legion, and through its development, created several Iron Man Armors, which were the Mark VIII, Mark IX, Mark X, Mark XI, Mark XII, Mark XIII, and the Mark XIV all with various designs and purposes. After the Mark XIV's completion, Stark proceeded to working on his next armor, the Mark XV

Stark designed the Mark XV to specialize in Stealth, and created a built in Cloaking System into suit's armor to enable it to blend in with its environment. Tony also named the suit "Sneaky" for it's stealth capabilities.

It was presumed that the armor was tested a number of times before it was fully functional and ready for combat.

Completion and Storage

After completing the armor, Stark stored it in the Hall of Armors Extension beneath his Malibu House, where all the other previous Iron Man Armors he completed were stored in as well.

With Sneaky's completion, Stark proceeded to create it's successor, the Mark XVI, also known as "Nightclub".

Iron Man 3

Malibu Raid

When Tony's Malibu Mansion was raided, and later destroyed, the Mark XV along with the rest of the Iron Legion were still stored safely within the Hall of Armors Extension, as it was left undamaged during the attack. The chamber was still intact, completely sealed, and concealed from view.

This was part of Stark's plan, in which the Iron Legion was to be used later after he uncovered the truth behind the Mandarin and A.I.M.

Activation of the "House Party Protocol"

After Tony and Rhodey uncovered the plans of A.I.M. and saved President Ellis, they both head to the Roxxon Oil Rig' to confront Aldrich Killian. Stark then orders J.A.R.V.I.S. to initiate the "House Party Protocol" and the armors fly out of the chamber and head towards the oil rig. When the pair reach the area, they go undercover but are soon caught by Killian's henchmen and are quickly overwhelmed.

Arrival with the Iron Legion

As Tony and Rhodey are surrounded by Extremis Soldiers, small lights appear in the distance, and it is revealed to be the Iron Legion. The armors, including the Mark XV, arrive at the scene just in time and quickly surround the Oil Rig. Tony makes a remark, and then orders J.A.R.V.I.S. to "Target all Extremis heat signatures. Disable with extreme prejudice." J.A.R.V.I.S. responds with "Yes sir!" which echoes throughout all the armors. Tony gives the final order and a battle ensues.

Battle Damage and Destruction

The Mark XV, together with various other armors fly around the area targeting and attacking several Extremis Soldiers along the way, by blasting them with the armor's Repulsors as well as utilizing hand-to-hand combat.[1]

At some point during the battle, the suit lost its left leg to an Extremis Soldier but continued to function. Later, Sneaky was called on by J.A.R.V.I.S. to save Tony and help him escape from the detonation of the Mark XLII.

After donning the armor, Tony lost flight control due to the armor's missing pieces and fell to the ground. The crash completely destroys the Mark XV, but succeeds in breaking Tony's fall, leaving only the armor's right gauntlet attached him.[1]
